Definitions

  • the invention relates to a method for blunt splicing and a device for carrying out the method according to the preamble of claims 1 and 7.
  • butt splicer The device according to the invention for blunt splicing ("butt splicer") is part of a Splicer, which can be used in different areas.
  • a special one Application relates to the production of steel and textile corduroy carcasses for passenger cars and Truck tires.
  • Another field of application relates to fiber-reinforced rubber sheets for the V-belt manufacturing.
  • the joining of the sections can be done overlapping. It is easy to see that overlapping is a waste of material, which in the end can be considerable in large-scale production. Also, an overlap of the carcass material results in an imbalance of the tires made therefrom. In the production of tires special precautions are required. In order to avoid these disadvantages resulting from an overlap of the carcass material, it is endeavored to butt the sections of the rubber-coated cord webs together.
  • U.S. Patent 4,867,823 describes the butt joining of rubberized fabric sections. According to this method, conical rollers are moved under pressure over the loosely facing ends. Due to the oblique angle a pressing together of the ends is to be achieved. This transverse movement is associated with a certain amount of time. Therefore, the otherwise continuous conveyor belt operation must be interrupted during the lateral rolling.
  • DE-OS 23 59 131 is a device for blunt connection of under 90 ° rectilinear ends of two vulcanizable, parallel reinforcing ropes of textile or steel containing rubber sheets, each with one above and below the web ends respectively arranged pair of jaws, the jaws horizontal to each other and are movable from each other, and wherein the two pairs of jaws are movable vertically relative to each other and from each other.
  • the movement of the jaws toward and away from one another is realized by means of slanted planes along which the jaws slide.
  • EP 0 676 274 A2 describes the butt joining of rubberized fabric sections.
  • intermeshing pairs of jaws push together the opposite ends by means of a rotary and push motion.
  • the pairs of jaws are elastically supported by pressurized rubber hose inside pressure.
  • Patent Abstracts of Japan, vol. 008, no. 274 (M-345), Dec. 14, 1984 (1984-12-14) & JP 59145128 disclose a similar process wherein an overlapping splice is created with intermeshing pairs of jaws becomes.
  • the pairs of jaws are moved horizontally and vertically linearly.
  • JP 51 59980 A shows in total two splice methods. In the first method, the compression is achieved by inflatable bellows, which are blocked in one direction to support their expansion, and in the second method, the contact pressure is again generated by spring-loaded pairs of jaws, which are pressed against each other via lever drives.
  • the invention is based on the object, the Connect sections so that the connection has a high and constant strength has.
  • the actual splicing device 32 (Fig. 3) consists of the splice shell 14 and two Splice bases 18 and 18 '.
  • the splice shell 14 is constructed on the mounted on the drum axis Side walls 34 and 34 '(see also Fig. 2), a traverse connecting them 36, a pneumatically actuated, positive lock 38 (FIG. 2), with the drum bottom, and a pneumatically actuated pivot mechanism 40 ( Figure 2).
  • the splice blades 46 and 46 ' are formed such that they form in the raised position of the splice shell 14 on its underside a transverse, central gap. Variant: that they are already evenly toothed on the underside in the middle. (This applies only to the splice shell 14)
  • each splice bottom 18, 18' are on the top formed in the same way as the splice blades 46 and 46 'of the splice shell 14th on the bottom.
  • Splice blades 46 and 46 '; 56 and 56 'of the splice upper 14 and -Schvons 18 and 18' have a thickness of 2 mm and are arranged on the hollow shafts 44 and 54 such that in each case the right splice blades 46 of the splice shell 14 on the right splice blades 56 of the splice lower part 18th are positioned.
  • the left splice blades 46 'and 56' are positioned accordingly.
  • the splice shell 14 In the initial position (splice preparation), the splice shell 14 is in the raised position, the splicing base 18 located in the working position is vertically below it, the tube 40 being vented. The gap between the splice blades 46 and 46 'and 56 and 56' is open.
  • the stop bar 42 lowers on the splice lower part 18.
  • the roller conveyor 20, controlled by the photocell 24 with position detection conveys the end of the layer web 28 back against the stop bar 42. Parallel to this operation, the beginning of the section 12 to be spliced is transported by the feed belt conveyor 4, controlled by the photocell 6 with position detection, against the front edge of the stop bar 42.
  • the splice shell 14 lowers on the splice lower part 18, wherein at the same time Stop bar 42 lifts.
  • the two sections to be spliced are thus non-positive fixed.
  • the tube 40 in the splice bottom 18 is vented and pushes the splice blades 56 and 56 'together in the splice region, wherein the non-positively fixed layer ends and the splice blades 46 and 46 'of the splice shell 14 are taken.
  • the splicing drum 8 is rotated by 180 °, wherein the Splice shell 14 via the lock 38 (Fig. 2) runs along, their position to Splice base 18 so not changed.
  • the section 28 fills the compensation loop 26, which according to their degree of filling the Unwinding station controls.
  • the brush roller 30 may solve a adhering to the drum 8 section 28th
  • the second splice lower part 18 After rotation of the splicing drum 8 by 180 °, the second splice lower part 18 'has assumed the working position and the entire splicing process is repeated.
  • the Zuindustrialgurtsleyer 4 has now introduced a new section 12. During the rotational movement of the splicing drum 8, the pressure roller 16 is lifted. Only at the end of the movement, during the return transport of the section 28 against the back of the stop bar 42 is the pressure roller 16 on the section 28 at.
